3D-grafics picture a first approach for making modular roof elements.
For pictures of a first test see First test beam structure
This design incorporates 3 basic ideas: -Double layer roof, to prevent heat from the top roof sheets radiate downwards
-Top layer is from smaller size roof sheets, giving the option to use left-over parts from roofing
-The roof module has a strong wooden member that links up with the modules which it is aligned.
